Access Point 1231

Good evening,I am contacting you for consultation, at our facilities are mounted Access Point Model 1231 and Model 1242, which are connected to omni-directional antennas, these antennas might suffer vandalism or theft, as I learned that I have broken this antenna, there is some kind of log or alarm to tell me to my Access point that has no antenna, I put the case for both Access Point Access Point centralized and autonomous.Thank you very much
